WRITING-MACHINE;

Patented Oct. 9, 1917,

To all whom: it may concern Be it known that I, FRANK A. FEIERIJSEL, a citizen of'the United Stntes,,residin at Chicago, in the county of Cook and Sta of Illinois, have invented certain new and usethe accompanying ful Improvements in WritingTMachines, of which the following is :1 specification.

This invention re ates to writing machines and more particularly to improvements in striking mechanism therefor.

i It is an object of my invention to provide, in a. writing mechine means whereby the key and type bars are rigidly maintained in proper nlinement so that lateral movement, which might result in slurring the letters printed is effectivelyprevented.

A further object of my invention is the provision of a simple and efi'ective operating connection between the key and type burs, whereby the type may be caused to exert the desirable pressure-during the printinfi 0perationwith a minimum application 0 force at the'keys.

A still further object of my invention is the provision of a striking mechanism for writing machines involving n minimum number {of parts, whereby the munufncture of the machine is simplified and the weight thereof is materially reduced.

Further objects and advantages of my invention will be apparent as it is hotter understood by reference in the following specification when read in connection with drawing, illustrating! a preferred embodiment thereof, in which- Figure 1 is :i plan view otthcfrnme of the machine with the cooperating key and type bars and the means for nmiutaiuing the bars in proper alinement;

Fi 2 is nverticulsection on the line 22 of Fig.1; I

Fig. 3 is a horizontal section on the line 3-3 of Fig.2;

Fi 4 is a. vertical section on the line 4-4 ofFignl; i

Fig. 5 Is a detail in perspective of no integral member to engage the contiguous extremities of the liey and. type hers and Fig. 6 is a detail in perspective of the means on the kc inns providing an operating connection ietween the-key and type bars- I Referring to the drawing, indicates a suituhle frame for supporting thevarious parts presently to be escribed. A shaft 2 is secured to the frame 1' adjacent the forword extremity thereof andpivotall supports t lurnhty of'keyburstl, eacii royidcd wlth a key '4 nt its outer end. he mper ends of the key bars-3.11m provided with upwardly extending arms 5 having slots 6 therein. Pirotally mounted on a shaft? reerwnrdl of the shaft 2 are n pluri lity of,bell-cranl le ers 8,each having type characters 9 near the extremities of one of the arms thereof and a curved extension 10st the extremities of the other nrms thereof, the extensions 10 being adapted to engage th'eslots 6 inthe arms5 of the keybnrs 3. Springs-11, secured to the key burst and. to nbase plate 12 of the frame 1 serve to maintain the key and type bars in their normal position.

From the foregoing it \rill'be apparent that. when one or more of the kc s 4 are depressed the corresponding key here 3 and bell crank levers 8 will be, rotated on their respective shafts 2 and 7 to .move the t characters 9 into engiigement with the n hon 13, impression-receiving mnterinlrl'i and platen 15, ,the'lntter elementsbeing illusr truied in dotted lines in the drawing. "During this operation the curved extcnsionslO of the bell-crank levers 8 slide in the slotsfi.

' ilv ,understood. sufiirientlevcrnge is ,pro-

vided to cause the type cl nrncters ll. to exert sufficient pressure at the printing point with .a minimum applicntion of force to thekeys, and a rigid connection between the key. and ty e hnrs'isnssurcd. v

' ilormniutnin theikey and typeoarslip proper nlinemcnt a spncipg Washer 16 is mounted on the shaft 9 between each .of the key here 3. A plate 17 is'secured to the frame 1 at 18 nnd isprovidrd with a plurnlity of slots 19 in which the extremities of the lwllcrnnk levers stare disposed. the plate 17 is provided with aplurnlitvor' 1ntcgrnl down-turned spl ced arms 20 hetween which the eontimious PXiIOIhihBS of the key bars tare disposed. A plateizi' its-secured to the frame at 22 adjacent"the-printing point and is rovided iyi'thrn plnrulity of spncedprms 23, proi'idmp; slotsm such of which the upper end of one of the arms of the bell-crank levers 8 is disposed. It will be understood 'from the foregoing that the key bars and the bell-crank levers 8, forming the type bars, are each guided at two separated points and that lateral movement thereof is therefore effectually prevented. The integral plate 17, havin guiding means for the contiguous ends of t e key and type bars, provides a simple and compact means for accomplishing the desired result.

It will be apparent that l have perfected an extremely simple and effective striking mechanism for writing machines, whereby numerous desirable results are obtained.

It will be further apparent that various changes may be made in the form, construction and arrangement of the parts Without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbeforc described being merely a preferred embodiment thereof.

I claim:

1. In a. writing machine, the combination of a frame, a shaft adjacent the forward extremity of said frame, a plurality of key bars pivotally mounted on said shaft, separating means on said shaft between said key bars, a plurality of type bars pivotally mounted rearwardly of said shaft, interengaging means on said key and type bars, whereby the latter are actuated, an integral. member having means thereon to engage said key and type bars to maintain them in proper alinement, and separate means engaging said type bars above said member to prevent lateral movement thereof.

2. In a writing machine, the combination of a plurality of pivoted type bars, a plurality of pivoted key bars, slidably interengaging means on said key and type bars, whereby the latter are actuated by the former separating means between said key bars at their pivotal points, means for engagi said key and type bars at their contiguous extremities to maintain them in proper alinement, and means to engage the opposite extremities of said type bars to prevent lateral movement thereof.

3. In a writin machine, the combination of a plurality of pivoted bell-crank levers, each provided with type characters adjacent the extremity of one arm thereof, a plurality of pivoted key bars having means thereon to em race the extremities of the other arms of said bell-crank levers, separatin means between said key bars at their pivota points, means for enga 'ng the extremities of said key bars and t e pivotal portions of said bell-crank levers to maintain the latter in proper alinement with said hey bars, and means engagin the ty e character-bearing arms of said he l-crank evers to prevent lateral movement thereof.

- 4. In a writing machine, the combination of a frame, a shaft adjacent the forward extremit of the frame, a plurality of key bars pivota ly mounted on said shaft, a shaft supported in said frame medially thereof, a plurality of type bars pivotally mounted on said second-mentioned shaft, interengaging means on-said key and type bars whereby the latter are actuated by the former, an angular plate ha ing slots to receive the pivotally mounted ends of said type bars and a downwardly turned portion having alined slots to receive extensions of said key bars, a platen with which said type bars coiiperate, and a slotted late adjacent said platen to prevent lat-crafmovement of the free endsof said type bars.
